The 28-year-old midfielder's commanding performances in the Bundesliga have caught the attention of the English sides, who are eager to bolster their squads with his tenacity and leadership.
German outlet Bild reported that Newcastle and Aston Villa have reached out to Karazor's representatives to discuss his contract details and gauge his interest in a potential move to the Premier League. However, the clubs have yet to make direct contact with Stuttgart, suggesting the interest remains in its early stages.
Karazor, who joined Stuttgart in 2019, has been a linchpin in their midfield, forming a dynamic partnership with Angelo Stiller.
His role as captain and consistent performances, including winning nine out of ten duels and setting up two goals in a recent Bundesliga match, have solidified his reputation as a reliable and influential figure.
Stuttgart, fresh off their German Cup triumph against Arminia Bielefeld, are determined to retain their star, with his contract running until 2028.
"No official offers have been made, but the interest from Newcastle and Aston Villa shows how highly Atakan is regarded," a source close to Stuttgart said. "He's happy here and focused on our goals, but the Premier League is always tempting."
Newcastle, aiming to mount a "genuine title challenge" next season, see Karazor as a perfect fit for their midfield rebuild, while Aston Villa are keen to add his experience to their ambitious project under Unai Emery.
Neither club has tabled a formal bid, but the coming weeks could see negotiations heat up as the transfer window progresses.
Stuttgart's coach Sebastian Hoeness praised Karazor's impact, saying after their German Cup win: "Atakan leads by example. His work rate and quality are vital to us."
The midfielder himself has remained tight-lipped on social media, with no recent posts addressing the transfer speculation, focusing instead on celebrating Stuttgart's recent successes.
Whether Newcastle or Aston Villa can pry Karazor away from Stuttgart remains uncertain, but his blend of defensive grit and playmaking ability makes him a hot prospect in the transfer market. Football fans will be watching closely to see if this Bundesliga gem makes a blockbuster move to England.
